In Hong Kong's highest court, five judges are deliberating whether to recognize same-sex marriages conducted overseas.
Their decision, expected later this year, could influence Asian financial hubs from Tokyo to Singapore to draft more inclusive laws as a draw for the diverse, global talent that multinational corporations from banks to technology giants are seeking to hire and retain.
"Corporates have a massive role to play. They still drive the conversation in a lot of these countries where the legislators aren't," said Janet Ledger, chief executive of Community Business, a not-for-profit organization that promotes diversity and inclusion in companies across Asia.
